We want to design a bandpass filter of bandwidth 7.5 kHz with a cascaded low pass filter (LPF) and high pass filter (HPF). What should the cut-off frequencies of each filter be?  

A JFET can be used as a voltage-controlled resistor by adjusting the drain voltage.

Assuming the diode is ideal. After an “infinite” amount of time, what is the DC level at the output, in volts?

Determine the current through the 300-Ohm resistor. Express your answer in milliamps (mA).   

A transformer must always bring down the voltage of the mains supply (wall power).
